Yuusha-chan no Bouken wa Owatteshimatta! 2

After vanquishing the Demon King, the proud heroine grows restless, her power stagnant yet haunted by vivid dreams of defeat and pleasure at the hands of demonic remnants. The sensations feel too real, igniting a forbidden craving that gnaws at her resolve. As the nights pass, the dreams grow darker, more insistent, until she surrenders to the ecstasy they promise, her mind and body succumbing to the very corruption she once fought.
